DENNY: A NEEDLE IN THE HAYSTACK OF HUMAN EVOLUTION.

DENNY: UNA AGUJA EN EL PAJAR DE LA EVOLUCIÓN HUMANA.

DENNY: UN AGO NEL PAGLIAIO DELL'EVOLUZIONE UMANA.

(English / Español / Italiano)

The Max Planck Institute for Evolutionary Anthropology did it again by publishing in Nature a couple of years ago the discovery of the first direct offspring of two different human species.

"Denny" (Denisova 11 for Science) was a teenage girl who lived 50,000 years ago in the Denisova cave (Altai) and left us at the age of 13.

His mother was a Neanderthal female and his father was a Denisovan. That makes Denny the first first-generation hybrid human found so far.

We know that Denisovans and Sapiens hybridised somewhere and sometime (very little is known about the mysterious Denisovans compared to other human species) because they left part of their genetic legacy in today's original human communities in Australia and Oceania.

We also know that Neanderthals and Sapiens hybridised and the proof is in our genetic map.

But in Denny's case, it is the first time that a direct (first generation) descendant of two different human species has been found.

What secrets did he keep?

We will be telling you about them as we get to know them. But for the time being, as expected, Denny was not alone 😉

El Instituto Max Planck de Antropología Evolutiva volvió a hacerlo publicando en Nature hace un par de años el descubrimiento de la primera hija directa de dos especies humanas distintas.

"Denny" (Denisova 11 para la Ciencia) era una adolescente que vivió hace 50.000 años en la cueva de Denisova (Altai) y nos dejó a la edad de 13 años.

Su mamá era una mujer neandertal y su papá era denisovano. Eso convierte a Denny en el primer humano híbrido de primera generación encontrado hasta el momento.

Sabemos que denisovanos y sapiens hibridaron en algún momento y en algún lugar (es muy poco lo que se conoce sobre los misteriosos denisovanos comparándolo con otras especies humanas) porque dejaron parte de su legado genético en las comunidades originarias humanas actuales de Australia y Oceanía.

Sabemos también que neandertales y sapiens hibridaron y la prueba está en nuestro mapa genético.

Pero en el caso de Denny es la primera vez que se encuentra a una descendiente directa (de primera generación) de dos especies humanas diferentes.

¿Qué secretos tenía guardados?

Os los vamos a ir contando conforme los vayamos conociendo. Pero de momento os adelantamos que, como era de esperar, Denny no estaba sola 😉

L'Istituto Max Planck per l'antropologia evolutiva lo ha fatto di nuovo, pubblicando su Nature un paio di anni fa la scoperta della prima discendenza diretta di due specie umane diverse.

"Denny" (Denisova 11 per la scienza) era un 'adolescente vissuta 50.000 anni fa nella grotta di Denisova (Altai) e ci ha lasciato all'età di 13 anni.

Sua madre era una femmina di Neanderthal e suo padre un Denisovano. Questo fa di Denny il primo ibrido umano di prima generazione finora trovato.

Sappiamo che i Denisovani e i Sapiens si sono ibridati da qualche parte e in qualche momento (si sa molto poco dei misteriosi Denisovani rispetto alle altre specie umane) perché hanno lasciato parte della loro eredità genetica nelle attuali comunità umane originarie in Australia e Oceania.

Sappiamo anche che Neanderthal e Sapiens si sono ibridati e la prova è nella nostra mappa genetica.

Ma nel caso di Denny, è la prima volta che viene trovato un discendente diretto (di prima generazione) di due specie umane diverse.

Quali segreti ha mantenuto?

Vi parleremo di loro man mano che li conosceremo. Ma per il momento, come previsto, Denny non era sola 😉

Un articolo pubblicato sulla rivista "Science" riporta l'attribuzione di una mandibola fossile scoperta a Taiwan a un Denisova. Un team di ricercatori ha condotto un'analisi di amminoacidi ancora presenti nella mandibola e nello smalto dei denti ancora presenti rilevando due varianti che costituivano proteine specifiche della specie Denisova. Sono varianti ancora presenti in alcune popolazioni asiatiche che hanno ereditato geni dai Denisova. Questa scoperta espande l'area in cui sono state trovate tracce di questa antica specie umana che per certi versi è ancora misteriosa.

Every so often I just get the urge to write a story set in the paleolithic but like the tropes are all from your classical high fantasy stories, with multiple humanoid species and cool big animals and a cool quest for the protagonists to go on

Why Africa?

Current evidence points to Homo sapiens developing in Africa about 300,000 years ago, but Homo Heidelbergensis who gave rise to us also lived in Eurasia, where they gave rise to the Neanderthals, and in Asia, where they gave rise to the Denisovans. Homo erectus, who gave rise to H. heidelbergensis, lived only in Africa, so H. heidelbergensis explored widely. But, why was it in Africa that H. sapiens developed?

It was established in about 1987 that mitochondrial DNA, which humans inherit from the egg cell they developed from, can be traced to on population in Africa that lived 200,000 to 150,000 years ago. Since the egg cell is typically from the mother, thus the whimsical nickname 'Mitochondrial Eve' was given to the unknown woman who gave rise to he mitochondrial DNA that modern humans have.

Newer studies, such as one published in 2023, are seeking to understand whether a single population of H. heidelbergensis gave rise to H. sapiens or if it was an intermingling of two or more population groups that gave rise to H. sapiens, such as groups that would come together occasionally for the exchange of members. These various populations would develop differently based on the environment of their typical range leading to minute differences between populations groups and the intermingling of these minor differences giving rise to a new species.

The current hypothesis as to why Neanderthals and Denisovans did not give rise to other hominids is that the glacial period of 100,000 years limited their range and thus their genetic diversity. The relatively mild climate of Africa during the glacial maximums allowed for genetic diversity as well as exchange of members between groups, keeping genetic flow moving between groups.

Even now, Sub-Saharan Africa has higher genetic diversity than the rest of the world combined. Curtis Marean, professor of paleoanthropology and associate director of the Institute of Human Origins at Arizona State University, said "The more genetic variation you have, the higher probability you have of something interesting evolving."

I would even argue against Arina being leading soloist "some day"...in my opinion she has potential, but not so much that we can certainly say she'll reach that level someday.

Yeah, she's not everyone's cup of tea. I will say that I've enjoyed watching her in smaller roles (like L'aurore in Coppélia). I think she has potential, like you said, and I could see her being at leading soloist level one day but I totally understand you having another opinion. She's not at the level of skill that Sergeenkova is or where Kokoreva, Sevenard, and Kovalyova were when they had that rank.

Sorry for the late reply btw!!

Un articolo pubblicato sulla rivista "Nature Communications" riporta varie considerazioni sulla variabilità degli ominini che abitarono nell'Asia orientale tra 300.000 e 50.000 anni fa e la proposta di una nuova specie chiamata Homo juluensis che include fossili scoperti in varie parti dell'Asia, inclusi quelli attribuiti ai Denisova. Il professor Christopher J. Bae dell'Università delle Hawaii a Mānoa e Xiujie Wu dell'Accademia delle Scienze cinese hanno cercato di fare ordine nell'organizzazione dei fossili di ominini asiatici del Tardo Quaternario con lo scopo di creare un sistema più chiaro che permetta di capire le specie umane che vissero in Asia.

Has Kokoreva ever done the Etudes ballerina part? I feel like she would be so charming in the variation.

I don’t think she has? But I need this casting. Her and that huge diagonal of chaine...chefs kiss. 

Thoughts on alyona kovalyova? 

She would not be my first choice to see in anything honestly. 

What do you think of Arina Denisova? She just came out of nowhere and suddenly was given big roles like O/O and Nikiya. Is she having a great sponsor or is Bolshoi that desperate to seek leggy dancers to prepare for Zakharova’s inevitable retirement? I personally found her unremarkable and too young for the roles she was given?

I’m not a fan. It’s a combination of a lot of things, the current aesthetic of ballet and Vaziev’s artistic choices, sponsorship, the corruption at MGAH, ‘preparation’ for the future…its a whole mess. I feel for her and Eva, because they both look like they’re completely out of their depth. 

how were denisova and sergeenkova’s nikiya debuts?

Sergeenkova’s was better, both were not it.

The world's oldest computer found under the sea is a mysterious discovery of the 21st century by scientists

As a result of advancements in science and technology, today we are able to discover many unknown facts about the earth and the universe. However, there are still many secrets hidden in the world. It can be said without any doubt that the 21st century is more important than any other period in the history of science and technology. Many things have been discovered in this century, which have brought revolutionary changes in human life, and have given some ideas of prehistoric existence. Today's video kicks off with some of the best discoveries of the 21st century, including the enormity of Vietnam's San Dong Cave, an ancient underwater civilization found in Denmark.rede more...

The telegram channels are saying they're rushing to promote her before the change in leadership, because the new ones don't like her as much.

So sorry for the late reply!!!

Yes, I've also heard on some Russian forums that that's a likely reason for Arina Denisova's promotion. It's been months and I'm still pretty disappointed by this choice. It's just too early for her and I also think it opens Arina up to even more criticism than she already gets and at such a young age.
